SPECIFICATION forming part of Letters Patent No. 448,498, dated March17, 1891.

Application filed August 28, 1890. Serial No. 362,874. (No model.)

To aZZ whom it may concern:

Be it known that I, J OSEPH M. BROI-IARD, a citizen of the UnitedStates, residing at Clarksburg, in the county of Harrison and State ofest Virginia, have invented new and useful Improvements inSash-Fasteners, of which the following is a specification.

My invention relates to that class of fasteners employed for looking amovable window-sash and holding the same either in a closed position orat any point to which it may be adjusted.

It is the purpose of my said invention to 7 provide a novel and simpledevice of this charaeteigwherebythe sash maybe securely locked at anypoint within the jamb or frame without requiring the use of springs orthe formation of interlocking apertures in the jamb within which thelocking member of the fastener must enter, whereby the sash can only besecured at certain specified points.

The invention consists, to these ends, in the several novel features ofconstruction and new combinations of parts, hereinafter fully set forth,and then definitely pointed out in the claims following thisspecification.

To enable others to understand and use my said invention, I will proceedto describe the samein detail, reference being had to the drawingsaccompanying this application, in which- Figure 1 is asectional view ofa window jamb or casing, showing the construction and application of thefastener, the latter being shown partly in section. Fig. 2 is a similarview showing the parts in the position they occupy when locked. Fig. 3is a detail view showing the parts of the fastener separated from thesash and from one another.

In the said drawings, the referencenumeral 1 denotes the casing or jambof an ordinary window, and the numeral 2 designates the sash or themovable member thereof, which rises and falls within the casing in theusual manner. Within the vertical bar of the sash is formed a recess orchamber, within which is inserted the fastener consisting of two similarsemi-cylindrical metallic bars 3 and 4:, fitting in said recesses insuch manner as to hold their faces in contact and at the same timepermit the free movement of one of said bars in the direction of itslength. Upon the outer end of the bar 3 is formed or mounted a flatplate 5, lying in a shallow recess in the sash, whereby its surface issubstantially flush with the outer face of said sash, to which it isfastened by one or more screws 6. Upon the outer end of the bar t ismounted a similar flat plate 7, also lying in a recess in the edge ofthe sash and flush therewith like the plate 5, but wholly disconnectedfrom the frame. Upon the inner end of the bar 3 is pivotally mounted acam-lever 8, which lies against the flat face of the said bar and issupported by a pivot 9, set therein and formed thereon. This cam-leveris formed of a flat plate of metal of suitable thickness and lies in arecess between the two half-round bars 3 and 4, formed by cutting awaythe rear end of the bar 4:, thereby forming a shoulder 10, against whichthe edge of the cam impinges. The inner ends of these two bars 3 and 4project through the inner face of the sash-bar, thus exposing the leverto view and permitting it to be operated by means of a handle orprolongation 12. By throwing the lever away from the sash the edge ofthe cam is driven against the shoulder 10 of the bar 4, thereby forcingsaid bar outward and pressing the flat plate 7 against the jamb orcasing with such force as to hold the window firmly at any point by thefrictional contact alone. be restored to its normal position and thelocking-plate 7 will be withdrawn and returned to the recess in the sashby the contact with the jamb alone, there being no obstacle orresistance to its movement the moment the lever is thrown downward.

This form of lock is simple, certain in operation, and of comparativelyinexpensive construction and application.

Rectilinear movement of the bar a is insured by forming a rib 13 uponone part of the duplex. sash-locking device and a groove or channel 14.-in the other adapted to receive said rib. These engaging parts may, ifde sired, be dovetailed; but I prefer to make them as shown in thedrawings, that being the simplest and least expensive form.

What I'claim is- 1. In a sash-fastener, the combination of Uponreleasing the lever the bar will Lil two substantially similar bars tobe inserted in a recess or bore in the sash and onehaving means tofirmly connect it with the sash, and a cam-lever pivoted upon one of thebars and having its edge constructed to bear against an abutment orshoulder on the other bar for projecting the latteragainst the Winclow-jmnb, substantially as described.

2. In EL sash-fastener, the combination of' two substantially similarbars to be inserted in a recess or bore in the sash and one having meansto firmly connect it With the sash, and a cam-lever pivoted upon one ofthe bars and having its edge constructed to bear against anabutment orshoulder on the other bar for projecting the latter against thewindoW-jzunb, one of said bars formed with a rib and the other with agroove, for operation substantially as described.

In testimony whereof I have affixed my 7 signaturein presence of twoWitnesses.
